Green Air no longer carries ultrasonic foggers. For fogger purchase please contact Frappa at (450)829-1177. We will continue to host information on the foggers to help promote these alternative growing methods.

Want to have roots like this?

Of course you do................

    and you can


The micro-fog will be completely absorbed by the plant through its capillary root hairs. Notice the ultra-fine root hairs that have grown on this lettuce.
At 26 days these examples demonstrate the astonishing distinction between media grown roots (left) traditional hydroponic (middle) and the micro-fog method (right). 


This is all you need. A bucket for a top off reservoir, the fog unit, and whatever kind of hydro chamber you want to fog.



We recommend that you use a timer or humidity controller to cycle the fogger on and off as needed, especially in small enclosures, to conserve solution and to avoid too much humidity. In most cases it is not necessary to introduce fog continuously.


Use the CYCLESTAT- 4P to operate your fogger based on a repeat timing cycle.

Cyclestats offer a user adjustable timing sequence.

The Green Air Products RHC relative humidity controller is the best way to keep humidity values at the optimum level automatically.


Whole Room Fogger



Ultrasonic Fog Generators (UFG) use ultrasonic technology to produce a fog composed of 5 micron and less sized water particles, thus avoiding the damaging phenomenon of "free water" drops as is the case in other technologies. The water particle size is a critical parameter in most agricultural applications since the presence of "free water" drops are often extremely injurious to plant materials

The Dry Fog behaves as a fluid in gaseous phase which is capable of deep penetration of minute spaces. This eliminates the free water which contributes to contamination, disease and pollution in industrial agriculture applications of solutions using traditional methods. The UFG is a low-maintenance combination of solid state electronics and modular construction of few moving parts, with no small apertures or pressure requirements. Easy to install and use.



The advantages of soil-less and detached media for propagation and cultivation of many horticultural crops are self-evident. All these systems, including many types of hydroponic units, rely on the use of a solid medium to support the roots. Aeroponics is a unique method of propagating and growing plants with their root systems enclosed within a mist chamber.

This is a new, improved, aeroponics system, based on ultrasonic-generated fine fog. The system consists of a module made of lower opaque plastic compartment which contains the roots, and an upper transparent hood for the shoots. The modules are fed from underneath by a central ultrasonic fog generator, which releases a fine, 1-5m droplet, fog. The fog is equally distributed into the lower and upper compartments of the module. The system is modular, electronically controlled, and the fog can be applied intermittently, at any pre-set cycle. Water consumption is low (500 ml/h at continuous operation), as is electrical power requirement (ca. 50 w/h). The aeroponics system allows the application of fog either to the base of cuttings and root-systems, or the shoots, or both.

This improved fog-aeroponics system has been used successfully for years for:

(1) rooting of chrysanthemum, kalanchoe, carnation and mung-bean cuttings.
(2) hardening and liner production for chrysanthemum and kalanchoe.
(3) growing mature, flowering, tomato plants.
(4) germination and initial growth of mung-bean and radish sprouts.

The cuttings produced good, well branched, normal root systems. Rooted cuttings were transferred to a standard potting mixture and allowed to develop in the aeroponics system. Top and root fresh weight of these liners was twice as much as liners growing without fog. Large cuttings of mature tomato plants rooted and developed well for at least 3-4 weeks, and fruit-set occurred. Seed germination in the aeroponics unit was rapid, producing uniform sprouts.

The new fog-aeroponic system is an advanced, modular, multi-purpose propagation and growing unit. This is due to both its constructional, mechanical, and physiological horticultural versatility. Mechanically, it is a simple, non-expensive and fully controlled system. Unlike traditional foggers, the ultrasonic-generated fog system alleviates the need for high water pressure and expensive filtration devices. Water and electrical power consumption is low, and the system is completely safe. Physiologically, it provides for maximal aeration, combined with adequate water supply to the plant. These advantages allow uninterrupted growth of both roots and shoots. The fog-aeroponics system, therefore, seems to be advantageous for various types of propagation programs and horticultural activities, especially for the following: efficient rooting of cuttings, an alternative for standard mist and fog propagation, hardening and liner production, production of specific root crops and root-derived products, high-humidity growing of specific plants (e.g. tropical and epiphytes), tissue cultures, controlled horticulture in space modules, hobbyists, and root research programs.




Install the unit on a wall making sure the wall plate is level. Do not connect the E.B.U. and fan. Add water to the water container. Make sure the ball valve is open. Adjust the screws on the wall plate to adjust the water level. Do not touch the float. The water level should be at the middle line in the torch window. Connect the large reservoir to the small water container. Connect the fan. Connect the E.B.U. to the transformer. Connect the transformer to the power supply. Close the door on the unit. Connect the hose from the fog exhaust hole to the garden.


Make sure the large water reservoir always contains water. The small water container will be empty in approximately one hour. Make sure that any product you add to the water is fully liquid. A 120 mesh filter can be used between the large water reservoir and the small water container. Put the large water reservoir a few feet above the small water container. It will fill up by gravity. Always make sure the ball valve is open. Always make sure the water level in the torch is in the middle of the window. The fan must be ON at all times. The E.B.U. should be connected to the timer.


The E.B.U. is HOT. Do not touch. The E.B.U. must not run out of water or it will burn out. The unit is NOT under warranty under these conditions. Do not unscrew the E.B.U. When the E.B.U. is working the fan must be ON or it will burn out. The unit is NOT under warranty under these conditions. Always keep the transformer far away from the unit in case of water leaks. Always keep clear of children and pets. When Cleaning Always: - unplug the transformer - unplug the fan - close the ball valve - disconnect the E.B.U. electrical connection - empty the torch by disconnecting the hose from the ball valve. Be careful when you disconnect the hose as water will come instantly.


Fill the torch with distilled white vinegar (6% solutions are available at your local grocery store). Fill to the top of the viewing window. Let soak for 10-30 minutes, then shake and drain. Inspect the sensor, walls, and the EBU through the viewing window. A flashlight may help. Make sure all salts and deposits are gone. Repeat the above steps if necessary.

Frequency of cleaning is determined by the nutrients and solution(s) used in the fogging machine. Example: Foggers using de-ionized water only, will not need to be cleaned very often; while those using fertilizers, will need to be cleaned more frequently. We recommend cleaning your fogger every 1-4 weeks or as needed.

NOTE: Effectiveness of your fogger may be reduced when using materials, such as fertilizer and supplements, that are not fully soluble. Your fogger will need cleaning more often.
